To all whom it may concern: i i

Be it known that I, ALLEN T. Ransom, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Wave and Gravity Motor, of which the following is a full, clear, andex'act description.

' This invention relates to certain im rovements in wave and gravity motors, an more particularly to a special'arrangement of parts, "whereby the power of the Waves of .figures, and in which the sea or ocean is utilized alternately with I the power of gravity, for operating mechan- 18111 and utilizing said mechanism directly Figure l is a side elevation of-a mechanism constructed in accordance with my invention, a portion thereof being shown in section; Fig. 2 is a top plan View thereof, the supporting lioor being removed; and Fig. 3 is a detail section of the outlet valve of the compressor. s

Myimproved mechanism is connected to any suitable support at any point where the variation in the water level is continually changing, due to the action of waves, tide, or other causes. As illustrated, provide a )latform or floor 1i). mounted u )on an suitable form of standards, piers, or posts 11, and to the und r side of the platform .10 is secured the mechanism constituting the essential portion of my inventiom- Two hangers 12 are bolted or otherwise rigidly summed to the under side'of the platform 10, and thcsohanrers support two parallel shafts and 14-. The shaft 13 carries a drum 1?) and a gear wheel 16, while the shaft it has one or-morc cranks l7 and a gear wheel lpot smaller diameter than the gear wheel 10. Beneath the drum 1?) is a float 19 comiccted by a cord 20 to a counterbalapcing weight'2l. The cord extends enin the direction.

tircly around the drum once, and itii ends depend therefrom and are held taut by the weightand the float. The platform, together with one of the posts 11, support one or more air compressor c .linders 2-2 at substantially the same e1eva-.

tion as theitwo shafts 13 and 14. Within each cylinder is a corresponding piston 23,

and the piston rod24 is connected by a connecting. rod 25 to the corresponding crank 1'? of the shaft 14'. The cylinder head opposite to the shafts, is preferably provided with flanges 26, which are rigidly bolted to the post 11, and the opposite end of the cylinder is provided with a spider 27 for guiding the pisto n rod. The last-mentioned end of the cylinder is supported from the latform hy a su'itahle bolt 28, which ten 5 to hold the latter more steady. The end of the cylinder opposite to the shafts is pro-- vided with a valve-controlled outlet passage communicating with an upwardly-extendin; conduit 29 leading to a manifold 30. Al

' o'f the-separate compressors have their own discharge conduits 29 leading to the manifold 30, and the manifold is connected by a conduit 31 to a suitable storage tank 32. The air may be drawn oil from a storage tank through a valve-controlled c ndnit 33 and led to any point at which it-is desired to use p the same.

The weight-and float are so proportioned toeach other that a lowering of the water. level causes a lowering of the float and the raising of the weight, while when the Water level rises, the weight 21 is sufficiently heavy to cause a positive rotation of the shaft 1-? Thus the weight operates to'rotate the shaft in one direction by gravity and the float operates to rotate the shaft i'n-tne opposite direction by the recedence of the waves. In case a plurality of cranks 12'' are employed, theyare at different angles, so as to render the load on the shaft more uniform. v

,To simplify the construction to the minimum and avoid the use of complicated valves, one end of each pump eylinderis left open and the piston is so constructed that the air may pass the piston during the n' 'ovement of thellattci' in. one direction. Thus-it is not necessary to employ any inlet ralve'othcr than the piston WEISl'lGI.- The outlet valve is preferably constructed sub stantially as shown in F lg. 3. Within the outlet passage is a plug 34- having a conical -readily pass the plug, and the plug carries Patent:

valve seat, and upon this seat rests a weighted valve 35, which may be' lifted by the,ai.r pressure to permit the air to it from the cylinder. The valve is slightly smaller than the bore of the plug, so that air may a downwardly-cxtendingfhool; or stem 36, which engages withithe lower end of the valve and preventsithe valve from-being forced u into the pipe or in any other way displaced by the compressed air.

Having thus described my invention, I-'

claim as new and desire to secure by'lietters tion between the tank and cylinder, a piston in the cylinder, and a pitman connecting the piston rod With the said crank.

2' An apparatus of the character described, comprising an elevated latform, hangers depending from the'plat orm; two parallel shafts mounted in the hangers, one of the shafts being provided with two-cranlrs set at, different anggies; gearing connecting the shafts, a drum on one shaft, a cable extending around the drum, a Wei ht on one end of the cable, a float on the ot er end at sald cable, two air compressor cylinders arranged below the platform, pistons in theieylinders,

pitmen connecting the piston rods with the said (Franks, a manifold, a valved cohnection between each cylinder and the manifold, and a stm'age tank with which the manifold is connecte In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
